Research

My primary research interests are in
computer vision. I am also very interested in more general questions in AI and
machine learning. My current research topics include:

Human Recognition: We
are developing computer algorithms to recognize human at multiple levels of
abstractions: from the basic body limb tracking, to human identification, to
gesture recognition, to activity inference. The ultimate goal is to develop
computation algorithms to understand human behavior in video.

Image
Segmentation and Object Recognition: Our research is motivated by two sets
of questions,1) how to extract “interesting” patterns from data,
and 2) how to guide the grouping process to achieve specific vision tasks, such
as recognizing familiar object shapes. In this direction, we have been pursuing
a line of research building upon spectral graph theory.
